Converting Between Moles, Atoms, and Molecules
Tyler DeWitt・11 minutes read
Atoms and molecules are compared as particles and converted using moles and atoms, with two methods - a direct one and conversion factors. Calculations use scientific notation and significant figures, recommending a calculator for efficiency, resulting in answers expressed in terms of atoms or moles. Practices converting between moles and atoms are provided, with a follow-up video for additional examples.
